Question

(t+3)-(t – 7)—t /2 при t=-12

Answer 1

Ответ:

(-12+3)-(-12-7)-12/2=(-9)-(-19)-6=-9+19-6=4

Answer 2

To evaluate the expression (t+3)-(t - 7)-t/2 when t = -12, we substitute -12 for t in the expression and perform the calculations.

(t+3) - (t - 7) - t/2

=(-12 + 3) - (-12 - 7) - (-12 / 2)

=(-9) - (-19) - (-6)

=-9 + 19 + 6

=16

Therefore, when t = -12, the expression (t+3)-(t - 7)-t/2 evaluates to 16.
